    • UNDAUNTED: The Forgotten Giants of the Allegheny Observatory Official Movie Trailer

      01:16

      from Dan Handley / Added

      UNDAUNTED: The Forgotten Giants of the Allegheny Observatory tells the remarkable stories of Samuel Pierpont Langley, John and Phoebe Brashear, and James Edward Keeler. Despite catastrophic setbacks and unrelenting hardships, these determined individuals defied the odds to ultimately make world-changing contributions to science and technology. Among the many accomplishments associated with the Allegheny Observatory are the establishment of standard time zones, the founding of astrophysics, major contributions to the invention of aviation, advances in solar research, precision star distance mapping, and discoveries in planetary science. A film by Dan Handley; William Peduto, Executive Producer; Mark Knobil and Jeff Garton, Directors of Photography; Original Musical Score by Scott Michael Burns. Features interviews with Dr. Neil deGrasse Tyson, astrophysicist at the American Museum of Natural History and Dr. Tom Crouch, Senior Curator of Early Aviation at the Smithsonian Institution National Air and Space Museum. Produced in association with the Senator John Heinz History Center. To be released in April, 2012. www.UNDAUNTEDtheMovie.com. The original Allegheny Observatory was established in 1859 in Allegheny City, Pennsylvania, an industrial city just north of where the Allegheny and Monongahela Rivers meet to form the Ohio River. A newer, larger Allegheny Observatory was built several miles away atop a hill in Pittsburgh’s Riverview Park between 1900 and 1912. Since 1867, the Allegheny Observatory has been owned and operated as an active research institution by the University of Pittsburgh.

      • A Tumbling Satellite

        In this timelapse video a passing satellite is captured while orbiting the Earth, tumbling around it self and flashing in the sky. Many satellites do not have a constant brightness, they give off flashes which are often at regular times. As described by the Satellite Observers (http://www.satobs.org/tumble/tumbleintro.html) this flashing behavior is caused by the rotation of the satellite around its rotation axis. The satellite's metallic surfaces act as mirrors for the sun. Measuring the period between flashes give an approximation for the satellite's rotation period. In this starry night of La Palma, Canary Islands, stars rise over the famous Isaac Newton Telescope in the observatory complex located on the top of the island. The V-shaped star configuration in this telephoto view is the head of constellation Taurus, the Bull, known as the Hyades star cluster. The bright star is Aldebaran, the Bull's eye. Based on the imaging time and camera information the satellite is identified by Ted Molczan of www.satobs.org: It is the Glonass navigation satellite Cosmos 2364 (98077A / 25593). The satellite's angular velocity was ~0.01 deg/second. The satellite altitude was 19148 km and 23631 km from the observer as it was captured near the horizon. Its orbital period is 675.73 minutes. The flashes probably are specular reflections from the solar array, caused by rotation of the satellite, which probably no longer operates. The timelapse is a 42-minute sequence starting around 1:30 UT, 2011 August 31. Each frame is 15 second exposure (+ 1s for intervals) and the video is 24 frames per second.

            • Map animation of the annular solar eclipse of May 20-21, 2012

              On May 20-21, 2012, an annular solar eclipse will be visible in China, Japan, and the western United States. This video is a map animation of the path of the eclipse across the western US. The antumbral shadow is rough because irregularities in the Moon's limb have been incorporated into the millions of calculations to produce this animation. You can find more maps and information about this eclipse at eclipse-maps.com

              • Aurora Activity over Northern Minnesota

                This video is taken with an all sky cam. The top of the image is North. The video is over saturated because of the brightness. I was not expecting any aurora activity since the sun is currently quiet but the sky exploded with aurora activity. This was not the usual aurora activity I see. It looked like a blanket of white light that flowed to the south and dissipated into pillows of light. I believe this activity was caused from a coronal hole high speed stream. You will also note a purple west-east line flow south as this aurora episode weakens. This was taken near Shevlin, Minnesota, USA on the night of Feb 18, 2012 at approximated 10PM CT with a Moonglow Technologies All Sky Cam.
